Mapping External DB Data Types to OutSystems Data Types
When connecting to external databases, OutSystems maps the external DB Data Types into OutSystems Data Types as follows:
| SQL Server | Oracle Data Type | MySQL Data Type | DB2 Data Type | OutSystems Data Type |
|---|---|---|---|---|
| Char Varchar Text Nchar Nvarchar Ntext Xml Decimal(Any,> 8) Numeric(Any,> 8) Real Float UniqueIdentifier Time Datetimeoffset | Char Varchar Varchar2 Clob Long Nchar NVarchar2 Nclob Number(Any,> 8) Float Binary_float Binary_double RowId URowId XmlType | Varchar Char Longtext Mediumtext Tinytext Text Enum Set Decimal(> 28,Any) Decimal(Any,> 8) Numeric(> 28,Any) Numeric(Any,> 8) Double Real Float Time | Character Varchar Clob DbClob Xml Decimal(> 28,Any) Decimal(Any,> 8) Numeric(> 28,Any) Numeric(Any,> 8) Float Real DecFloat Double Float Time Nchar Nvarchar NClob | Text |
| Tinyint Smallint Int Decimal(1-9,0) Numeric(1-9,0) | Number(2-9,0) | Tinyint(> 1) Smallint Mediumint Int Decimal(1-9,0) Numeric(1-9,0) | Integer Smallint Decimal(1-9,0) Numeric(1-9,0) | Integer |

For Decimal(M,D) or similar, M is the maximum number of digits (the precision) and D is the number of digits to the right of the decimal point (the scale).
